Multiple warning lights by model year

What owners say

Filed Oct 24, 2025 · Driver assistance, Electrical · CA

While driving on public roads, all dash warning lights illuminated simultaneously. The instrument cluster displayed “EyeSight OFF.” At the same time, the electronic parking brake engaged / the vehicle would not accelerate and required me to stop and shift to Park. The only way to restore drivability was to turn the vehicle off and restart. This has occurred intermittently, including in traffic, creating a serious safety hazard for myself and surrounding drivers.

I was stopped at a red light and the engine stalled. It read "FOR SAFETY, AUTO RESTART DISABLED". All warning lights on the dashboard lit up. I had to put the car in park and restart it in order to drive. I was honked at and put in a dangerous position. This has happened at least twice now.

my Subaru suddenly had numerous warning lights go on. Took it to the dealer and they said it was due to a recalled part: thermo control valve. They replaced it for free but said my head gaskets needed to be replaced after checking my oil for $4000 plus. I believe the recalled part caused the head gasket issue and shouldn’t have to pay also the mileage is only 66k

In April 2022 after owning the car for 4 weeks the Eyesight went out. I was told it was due to the thermal control module. That was replaced. I’m n June 2023 the AC went out. They said it was the blower motor. That was replaced. In September 2023 the AC went out again. At that point they found the cause was actually a fully melted fuse box and fuses. They replaced the fusebox and the entire AC system. I have had 3 batteries in the vehicle since March 2022. In December 2024 they found that my car needed an update and the update friend the transmission controls module. Then the starter went out at the same time. After that was fixed a week later all the lights in my dash came on and there were no safety features running in the vehicle. I reach out to Subaru and I was told this was all normal wear and tear in the vehicle and it just happens. A melted fuse box and safely features just randomly dying on a 4.5 year old car goes deeper than that. There has been almost $12000 in repaired performed on this car and the ones remaining are undiagnosed as they have never seen the codes before. This is a mush larger issue and Subaru refuses to do anything.

Good evening. My claim number for reported issues to Suburu USA is [XXX]. Issue; On 5 or 6 occasions our 2020 Suburu Forester vehicle stalled while we were driving it. The stall has happened both when we are stopped at a traffic light or slowing down for traffic or a traffic light or in one case, at a drive through. This is a safety issue as when we start to drive; the vehicle shuts down and the steering wheel locks up along with all dashboard lights coming on. Also, on at least 2 occasions a message came up to restart the car for our safety. Other cars around us were moving or had to wait for us which creates anger towards us and danger for other drivers if they try to drive around us. The issue has been ongoing since approximately July 2024. I am not able to add a MPH range below, but generally we are traveling 0-10 mph because we are usually braking or going from stop (at a light) and then trying to drive when the stall happens. The vehicle has been brought to XXXX XXXX in Hanover, Massachusetts each time and thus far, they have not been able to resolve the issue. Tonight, we dropped the vehicle off again due to the most recent stall that happened on Saturday [XXX] I have brought this to Suburu USA’s attention and other than the dealership trying to find the issue, not much has been done that I know of. I am hoping your office can inquire with Suburu because it is either an issue specific to our vehicle, or if not, there may be other suburus stalling out there which can lead to serious situations for other drivers. I feel compelled to report this because if there is a wider issue, it should be reviewed to protect others, INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Upon exiting freeway, all lights on car came on including brake light. When placed in park, the engine would rev. If placed in drive, car would drive without gas given. Car towed to Subaru dealership and diagnosed with thermo control valve defect which seems to be a known widespread issue. Thankfully I was located close to a Subaru dealership however if not, this could cause others to be stranded. Given this widespread issue, a recall should occur to fix this issue.

DEFECTIVE THERMOSTATIC CONTROL VALVE- This part NEEDS to be recalled. Manufacturer has extended the warranty on the part, so it was free to replace. Otherwise, it's a $1600 part. I'm thankful they covered the price, but upset that this KNOWN issue is preventable and they've been letting people continue to be put in danger for four years now?! Incident 1) I was driving 45 mph on a busy street when the car bucked & All engine lights turned on (not helpful to pinpoint a problem) EyeSight turned off (when I needed it most.) The car was worse than dead. I was desperate to get to the shoulder, so I slammed on the emergency lights. Horrified, I realized turning the wheel did almost nothing. I had to lean on the steering wheel to get to the shoulder. When I applied gas it would choppily accelerate, so instead i let the car coast. Since i had no gas, i was stuck in the middle of a side road. I put it in park and turned it off. Someone started walking up from the bad neighborhood, wanted me to get out so he could push the car. I said no, but It took a few minutes to talk him into leaving through the glass of my window. But, this time when i started it up the dash warning lights were off Incident 2) between Oct& Nov 2024 Intermittently all the dash lights turned on, no cruise control or Eyesight. Resolved on its own. No engine trouble acompanied these. Incident 3) Nov 5th, 2024. I started my car, warmed it up, and drove for about 3 minute's when all the dashlights lit up, Eyesight failed, and the whole engine acted like it was on choppy seas. This was at night in a rural area and I was barely able to guide the car to the right shoulder because the accelerator was not working at all. Ended up slashing up my tire and ruining my rim on the shoulder of the road since the car was barely maneuverable. I could have been killed or in an accident - where is the recall on this part?? Mileage at total failure : 46,434

The auto start stop feature has caused my car to shutdown with all lights lit on the dash in more than one scenario. In traffic on the freeway, I had my foot on the brake. It auto stopped. Then when the traffic was starting to move, I went to push the accelerator and the dashboard lights all lit up and the engine shut off completely. The car was still in drive but it was off. I had to shift the car into park and push the start button to start the engine back up. It has happened before at traffic lights with the same outcomes. I went to subaru dealer and they said some of the batteries were faulty and replaced it but that is not the issue since it is still happening. It is dangerous in traffic!

The thermo valve leaked into connector, causing engine to shut down abruptly to prevent overheating. This happened at 70 mph on interstate highway in traffic. Part was replaced with modified thermo valve later. Barely able to coast to narrow shoulder flanked by deep ditch, with vehicle very close to interstate traffic, so much so that exit from vehicle ill-advised. After towing, vehicle was serviced by Subaru dealer. At time of part failure many warning lights & messages appeared, but not before the event.

Multiple dashboard lights are on including starlink, eyesight, check engine, thermostat, and a blinking s. A quick Google search shows that this exact combination is a known issue. Safety concern is that all the accident prevention systems are down leaving me at risk.

I’ve owned my Subaru forester for over a year now. About 6 months ago while getting off an exit and at a light, when I went to accelerate my car died. All lights came off and no power to vehicle. I was able to restart and drive home. Called the dealer took it in and paid almost $2k for repairs. Today the same thing happened on the turnpike in stopped traffic. This could have been a bad accident.

While I was traveling I stopped at a rest area and when I restarted my car, my panel lit up like a Christmas tree. All my safety assist systems were disabled and my check engine light came on. When I got home I had my mechanic run the codes and it came back to the thermo control valve. This happened on 8-29-2023. I researched the problem and Subaru put out a service bulletin in February 2022 but never notified me. My car is out of warranty now and am forced to drive without my safety systems because, 1- they don’t carry the part in stock and 2- the cost to repair is over $1400.00. Subaru was aware of the problem but kept it quiet. I feel this is a scam and Subaru should recall this part. I was warned that my car could die at any time. I bought it for those very safety systems as I am a senior citizen and rely on them now.
